BUCKLE.

Applcationlerd February v5, 1926. Serial No.86,11f2.

This invention relates to a buckle, clasp or tfastener which is ,adapted tto connect the end of a. kstrap with another objectv .as for instancethetside of abrief case or 'traveling Qbaggor for connecting two endspfabelt.

iltisfthe ohject.of,this invention to provide a buckle for this ipurpose which isl comparatively ksimple'and inexpensivel in construction, which 4can be readily opened and permit of adjusting'the strap lengthwise on the buckle, :which is complactand neat in :appearance and will `reliably holdthe strap in its adjusted position and which permits `the strap to be adjusted readily up and Adown on the wall of tlielbriefcaseand also vinstantly unbuttoned fromthis wall wit-hout disturbing,thellengthwise adjustment of the buckle on the strap,` thus permitting of in- `stantaneous opening-"of ,the briefcase vwithout unbuckling the strap. i

lReferringto the `construction shown in Figs. 1, Q.,and 3the nume-ral 10 represents thefront wall of, a briefcase, 11 theupper flap which closesL downwardly .against I'the frontside ofthe wall 10,;'and 12oneiofv the' fastening; straps which is 'attached at.

i In the constructionfsl'iown in Figs; 1, 2 and 3 my improved buckle is organized :in lone formand lassociated'with.other parts so 1 that it is capable of beingjmoved vertically onthe front Ywall'of thebriefcase and the strap is also ycapable of being .adjusted lengthwiseonlthelbu'ckle. In the forni of Vthe buckle `as showlnliniFigs. 1,2 and Sltliei same comprises ajbase or plate 141 which is fadapted to be engaged on itsgfrontlside by theystrzap 12 :and is provided midway between its Alongitudinal 1edges with a `forwardly .projecting adjusting pin I15 adapted to engage with one or ,another oftheloni `gitudinal row of openings 18 for the pur pose ofladjusting the positionof jthisbuckle on thestrap and :adapting the vcapacity of the brief case to the volume of ,materiali which is to bestowedtherein. vOni its rear sideithe basecpl'ate 1 4:` is providedwith a buttonhaving'an elongated head`16 and a reduced neck 17 forming a Teshaped Astructure lwhich isadapted fto.engage with" one or y:amither of `.a ,longitudinal row lof Aslots 18 {formed in anjadjusting plate 19 which iis mountedl on thefrontwfall ofvthebrief case `andtherC-iby permitgof ,adjusting this buckle vertically on Athis vwall in order toadapt 'the size of the case to th'ejamount oflmaterial which islto becarried therein. Inthe nor- "mial vpositiiinfof:the head'lieandi slots 18 the same arevarrangedat anjanglefto each other. This necessitates turning the base` ,plate 14 slightlyin order to movegtlie same 4 ,into and 'out of? each Aslot 18 `and engage and `disengage lthe ends of the head with the underside Kofithe adjusting plate 19. This adjusting plateffo'rms thelweb of'fa channel.;

shaped', member, the flanges or legs 2O at i' |`opposite longitudinal edges o'fwhich are separts in theseveralviews of 4means whereby the strapfiswheld in engagement withI the adjusting vpin y154 and permits `,of detachmg this strapfrom thisV pinV and ,engaging different holes 13 of the strap ztherewith'` in order to Iobtain the desired length ofstrap tosuit the required capacity ,of'theA brief case or bag. Thesefeatures lof vconstruction which n e mbody `:my improve- Hinents are constructed asjfrollows.

rf he numeral 422represents two `longitudi- 1 nal lianges projecting forwardly from opposite longitudinal edges of the base 14 and confining the strap 12 therebetween. Pivotally mounted on the flanges 22 and arranged between the upper parts thereof 1s a cam or eccentric 23 which is adapted to bear against the adjacent part of the strap upon engaging its highest part therewith and thereby clamp the strap against the base 14, while upon turning this cam so as to disengage the high part thereof from the strap the latter will be released and free to be moved lengthwise upon the buckle after the same has been detached from the adjusting pin 15. lThis cam is turned by means of an operating arm 24 which projects downwardly therefrom and is preferably constructed in the form'of a thin, flexible sheet which is capable of springing. Near its lower end this operating arm is provided with an opening 25 which is adapted to receive t-he adjusting pin 15 upon swinging the arm downwardly over this pin in which the salient or high part of the cam or eccentric engages with the front side of the strap l2. In order to retain this arm and cam in this operative position Athe adjusting pin 15 is interlocked withthis arm for which purpose this pin is provided on its upper side with a locking notch 26 which is adapted to be engaged by the upper edge portion of the opening 25 in the operating arm, as shown in Fig. 2, thereby yieldingly locking the cam' in its clamped position. Upon lif ing or moving the lower end of the arm 24 away from the strap, the upper edge of the opening 25 in this arm will be disengaged from the locking notch 26 on the pin l5 and this arm may be then wholly disengaged from this pin and the cam moved into a released position relative to the strap, after which the strap may be moved lengthwise of the buckle, and then re-engaging the locking pin with one or another of the openings 13 in order to adapt the relative position of the strap and buckle to suit requirements. While thus engaging the operating arm with the notch of the adjusting pin and disengaging the same therefrom this arm is sprung or flexed somewhat, this be-v ing possible due to the sprmgy character ofV this arm which causes the operating arm to be yieldingly held in its locking position and still permits of easily opening as well as closing the buckle.

Additional means for holding the arm 24 in itslocked or closed position may be provided such as the locking lips y27 arranged on the front edges of the flanges 22 transversely in line with the adjusting pin 15 and bent inwardly toward this pin and into the path of the longitudinal edges of the arm 24. Upon pressing the operating arm 24 inwardly or rearwardly over the adjusting pin 15 the opposite-longitudinal edges of this arm at the same time are sprung past the inner ends of the locking lips 27 and into a position underneath the same, as shown in Fig. 3', thereby serving to yieldingly hold this arm in its closed position. Upon pressing the operating arm 24 outwardly the opposite longitudinal edge portions of the same bend or yield slightly, which together with the resilient character of the locking lips 27 and the flanges which carry the same, permit this arm to be disengaged from these klocking lips for opening the buckle preparatory to adjusting the strap thereon.

When it is desired to adjust the strap and buckle lengthwise one relatively to the other this is accomplished by simply pulling outward and upward on the free lower end of the strap which pull disengages the arm 24 from the locking lips 27 and the pin 15 and leaves the strap free from this pin and released from the cam and ready for instant readjustinent by inserting the pin 15 in one' ating arm 24 with the adjusting pin 15 and the side flanges of the base' this buckle is reliably held against accidental displacement and yet permits of easily opening and closing the buckle.

Obviously an upward pull of the strap on the buckle when the cam is in its closed position will cause the ylatter to grip with increasing fastness in proportion to the pull of the strap thereby insuring against slidage of the strap on the buckle in the event that there should be any wear in the holes of the" vstrap whichare in engagement with the adjusting pin 15.

Instead of mounting this buckle on the front wall of the brief case or bag so that the buckle'itself is adjustable vertically thereon, this buckle may be permanently attached to this wall by securing the base of the buckle to this wall 10 by means of'rivets 28, as shown in Fig. 7. y

If desired this buckle may also be employed toV advantage for connecting opposite ends ofa strap 29 by mounting one end kof this strap adjustably on the buckle in the manner in which this is done in Figs. 1, 2 and 3 while the other end of the-strap is attached to a loop 30 arranged in the lower end of the base 14, as shown in Figs. 4, 5 and 6.

I claim as my invention 4 kA buckle comprising a base adapted to be mounted on a member and to engage with the rear Side of a strap having a longitudinal row of openings, longitudinal anges arl ranged on opposite edges of said base and having inwardly projecting detent lips, a

ranged on said can] and adapted to engage 10 its opposite longitudinal edges with said lips and having an opening Which receives said pin and the edge of Which engages With said shoulder.

In testimony whereof I hereby afX my 15 signature.
